이기종 6G 네트워크에서 제한된 주파수 대역을 효율적으로 할당하여 간섭을 방지하는 동적 스펙트럼 접근(DSA) 알고리즘의 성능 평가
6G ネットワークにおいて、様々な異種アプリケーションの増加する周波数需要に対応するためには、動的スペクトラムアクセス(DSA)が重要である。本論文では、限られた周波数帯域を持つ複数の6G基地局を持つ異種無線ネットワークを考え、基地局の位置、カバレッジエリア、帯域幅要件を考慮しながら、干渉を回避しつつ連続的な周波数帯域を効率的に割り当てるDSAアルゴリズムを評価する。
A novel cloud-based architecture and multi-objective optimization algorithm for cognitive radio networks that reduces power consumption by 27.5%, global exposure by 34.3%, and spectrum usage by 34.5% compared to traditional cognitive radio networks.
TVWS networks have an energy efficiency 9-12 times higher than LTE networks in suburban and rural scenarios.
The maximum amplification gain that wireless repeaters can use without causing destructive positive feedback is restricted by the sum of inter-repeater channel amplitude gains, rather than the sum of path losses.
5G NR V2X 사이드링크 통신에서 숨겨진 노드 문제로 인한 패킷 충돌을 완화하기 위해 노드 간 자원 할당 정보 공유를 통한 협력적 자원 할당 방법을 제안한다.
The proposed FLARE framework allows participating devices to dynamically adjust their individual learning rates and local training iterations based on their instantaneous computing powers, mitigating the impact of device and data heterogeneity in wireless federated learning.
The authors design an adaptive client sampling algorithm for federated learning over wireless networks that tackles both system and statistical heterogeneity to minimize the wall-clock convergence time.
